It might have looked like aliens were hovering over the Puget Sound region Wednesday afternoon, but it was just another incredible display of lenticular clouds over Mt. Rainier.
Don Hoyt of TacomaWeatherCam.com has a web camera trained on the mountain and has posted this great time lapse video of the clouds forming:
It's certainly not the first time lenticular clouds have formed over Mt. Rainier. In fact, our web archives are full of examples from previous lenticular cloud shows.
The cloud is formed when warm, moist air runs into the surface of Mt. Rainier. The mountain's topography forces the air upward, which cools and condenses the air -- turning it into a cloud.
As the air sinks back on the other side of the mountain, it dries out and the cloud dissipates. That's why it just hangs over the summit area.
Although it looks like it is "hanging" over the mountain, air is continually flowing over the summit, as the video proves.
Enjoy! And if you get great photos of the event, we'd love to see them. You can submit them to YouNews.
